PORTABLE HEAD FOR IRRIGATION RISER/S.

Application filed 31113 29, 1920] Serial No. 399,792. g

T all w ho-m it mag concern Be it known that I, VICTOR E. NIooLAInEs, a citizen of theUn'ited States, residing at Lancaster, in the county of Los .Angeles and State of California, have invented new and useful Improvements in Portable Heads for Irrigation Risers, of which the following is specification.

I This invention particularly pertains to a adjacent the stand-pipe.

portions'of a field or area to be irrigated,

and stand-pipes or risers are arrangedat desired intervals in the pipe line for delivering water onto the surface of the ground The stand-pipes are ordinarily open at their upper ends and are fitted with cut-off valves arranged across the opening in such manner that on opening thevalve the water will discharge laterally all around the stand-pipe; the valves per mitting'theclosing and opening of any of the stand-pipes in'a series so that the water may be cut off at some points in the system and, allowed to flow in others according to requirements 'or convenience.

It is the object of this invention to pro vide a hydrant Which may be readily attached to a stand-pipe or removed therefrom and which may be easily carried from one stand-pipe to another in the series according-to which one is' to be employed in discharging the water, so that one hydrant will serve for any number of stand-pipes and thus obviating providing a hydrant for each standpipe.

Another object is to provide a construction whereby the hydrant may be readily turned, so that the spout or discharge portion thereof may be positioned to extend at any desired point around thestand-pipe.

A further object is to provide a simple and efiective means whereby the valve in the stand-pipe may be operated through the hydrant.

Other objects will appear hereinafter; The invention is illustrated in the accompanying drawings, inwhich:

Figure 1 is a view in vertical cross section PATENT mice;

showing the hydrant as detachablyc secured in place ona stand-pipe and showing the means foroperating the valve.

. Figure 2 is a plan viewof the valveseat member adapted to bepermanently mount- 1,.

ed on the stand-pipe as seen on line 2-2 o'fFigure 1. Figure 3 is a detail inverted horizontal section as seen on the line3-3 of Figure l. Figure 4 is a detail in elevation showing one of the clamps for detachably connecting the hydrant to the stand-pipe. l

More specifically, 0 indicates a stand-pipe which is here shown as formed of, concrete or tile, but whichmay be formed of wood, 3

metal, or any suitable material,and 6 indicates a metallic rim adapted to seat on the upper end of the stand-pipe 5 and is preferably permanently attached thereto. The

rim 6 comprises an annulus 7 which seats on the upper edge of the stand-pipe and has I projecting flanges 8lwhich extend beyond the outer face of the stand-pipe; the pro jecting portions 8 being spaced apart by openings or channels 9. "The rim is formed V with .a downwardly extending flange 10 adapted to project into the stand-pipe and to be secured thereto; the flange 10 being here shown as formed with a peripheral channel 11 disposed opposite a channel 12 on the inner face of the stand-pipe, which channels are filled with a cement .13 by which the rim is anchored on the stand-pipe and the joint between therim and stand-pipe sealed against leakage. Formed on the inner margin of the rim is an: upwardly 6X: tendingflange constituting a valve seat' 14 on which a-nupwardly opening disk valve 15 'is adapted to rest the valve being-provided witha packing ring 16 arranged to Y bear on they flange 1&1. 'The valv e 15 is mounted on aval've stem17 onwhich it is turnable; the valve stem projecting through a hub 18 on the "alve and having a staight sided head 19 adapted to seat on the upper face of the valve and having a collar 20 at the inner end of the hub 18 between which head and collar the valve is carried. lower end of the valve stem is threaded, as indicated at 21 and screwed into a yoke 22 formed on the rim. .The valve maybe opened or closed by rotating the 'stemto advance or retractit in its threaded bearing.

23 indicates the hydrant which embodies a cylindrical wall 24 a top wall 25, and a spout '26'projecting from one side thereof an in- The turned flange 27 being formed 011 the lower edge of the wall 24 and fitted with a packing ring28 adapted to seat on an annular upturned flange 29 formed on the rim 6 con'' centric With and spaced from the valve seat flange ll'. Mounted on hangers 30 carried by the hydrant, is a series of radially disposed rock shafts 31 on the inner ends of distant apart and sopositioned that the cams 3 2.1nay pass through the openings 9 in setting the hydrant in place on the 'rim, to

position the cams below the projections 8;

the hydrant being adapted to be turned to any desired position on the rinrwith the cams out of engagement therew th, to secure the hydrant on the rim'the canisare turned by operating'the handles 33 to engage the underside of the projections 8 and thereby clamp the hydrant in position, Extending through a packing gland 3:1 in the top of the hydrant is a stem 35, the upper end of whichis fitted; with a handle 36 and the lower end fitted witha socket 37 adapted to extend over and engage the head 19 of the valve stem 17 in such ma'nner that on rota tion of the stem 36 tl1e valve stem may be rotated to open orclose the valve. I

l The operation of the invention is apparent from the foregoing, vit being seen that the hydrant may be readily placed on ,thestandpipeand secured thereto by engaging the camswith the over-hanging or, projecting wportions of the rim 6 and that it maybe readily removedlby turning the cams to a disengaging position and thereafter rotat ing the hydrant to dispose the cams opposite the openings Q'WhereupOnt-he hydrant may be lifted clear of the stand-pipe. The stem 35 being slidable lengthwise and thepacking gland '34 permits it being readil engaged with the valve stem and by employing: the socket 37 the stem'35'will be free from eIi-.

gagement withthe alve stem onilifting-the hydrant clear of the. rim. WVhile Ifhave shown and described a specific embodiment of my invention, I do not limit myself to the exact details of construction shown, but may employ such changes or on said rim extending outwardly from the stand-pipe, a valve seating on said rim for.
